SUBJECT:
COMANCHE PEAK STEAM ELECTRIC STATION (CPSES)
DOCKET NOS. 50-445 AND 50-446 AUXILIAR/ FEEDWATER FLOW ORIFICE SDAR:
CP-89-004 (INTERIM REPORT)
Gentlemen:
On February 17, 1989, TV Electric verbally notified the NRC of a potential deficiency involving rotational parts of the Auxiliary Feedwater Flow Orifice Assembly.
Specifically, flow testing of auxiliary feedwater pump CP1-AFAPMD-02 indicates that the minimum flow orifice CP1-AFORB0-02 is passing greater flow than design flow which may adversely affect the rated flow required to the steam generators under accident conditions. On May 2, 1989, TV Electric verbally notified your Mr. S. P. Burris that the written report due to be submitted on May 1, 1989, would not be submitted until May 2, 1989, due to an administrative oversight.
This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e).
Further evaluation of this issue is required to determine potential impact on plant safety.
A final report on this issue will be submitted prior to fuel load.
Sincerely, William J. Cahill, Jr.
